You'll need to download a browser extension (Firefox or Chrome only) or Web widget to us this, but once you do, you'll have a system scanner that doesn't just look at one file at a time. It only works for Windows, naturally.

4. Last.fmwww.last.fm/
It might be the best music streaming services when it comes to social networking, and it's not bad with the music recommendations either. Better yet, Last.fm doesn't have any audio-based advertising. There are mobile versions and you can listen to it on your Xbox 360, as well. Read PCMag's review of Last.fm.

5. Groovesharkgrooveshark.com/
Does Grooveshark have every song ever recorded? Maybe not quite, but the music search and streaming site does a great job of finding tunes and letting you add them to playlists. The "Grooveshark Radio" recommendations play like other sites in this category, giving you more music that's similar to what you like.

6. Pandorawww.pandora.com
Pandora gives the power of the Music Genome Project to the people in the form of Internet radio that you can program to your tastes. Pandora offers 40 hours of free music listening per month, with advertisement, but, thankfully, the ads aren't worse than regular radio. And you can also find it on multiple devices, not just on the browser. Read PCMag's review of Pandora.

7. Slacker Radiowww.slacker.com/
PCMag's Editors' Choice for Internet-based music listening has a great interface, great sound quality, and all you could ask for free listening (paid users can even get music and albums on demand).  Read PCMag's review of Slacker Radio.

12. Mint.comwww.mint.com/
Intuit's Mint.com replaced Quicken.com for good reason.

It remains our Editors' Choice for personal finance tools.  Read PCMag's review of Mint.com.
